<div class="textblock"><p>A plot item, which displays a spectrogram. </p>
<p>A spectrogram displays 3-dimensional data, where the 3rd dimension ( the intensity ) is displayed using colors. The colors are calculated from the values using a color map.</p>
<p>On multi-core systems the performance of the image composition can often be improved by dividing the area into tiles - each of them rendered in a different thread ( see <a class="el" href="class_qwt_plot_item.html#a188ae18fbbce9adcf259ebe2f0de1f6b">QwtPlotItem::setRenderThreadCount()</a> ).</p>
<p>In ContourMode contour lines are painted for the contour levels.</p>
